In school: that's my son who's in his fourth year at West Point. I'll pass along your message though. Good luck with your mods. Jake West Point ROCKS! Nation's TOP COLLEGE per Forbes Magazine!! Graduation Day Parade 20 May 2010!!!

Yes. As I understand it, when GM went with roller rockers on the LT4 the knock module was picking up the noise from the RRs and interpreting it as knock and retarded the ignition timing. So the knock module was re-designed to be less sensitive to those false knock situations. From all I've...

Sensors #2 on either bank aren't heated, are they?? Isn't it just the #1 sensors on Banks 1 and 2 that are heated? Jake West Point ROCKS! Nation's TOP COLLEGE per Forbes Magazine!

The two names that surface most often are AI and LE (Lloyd Elliot), but there are others who offer comparable porting. Other porters have CNC programs which have shown excellent results. Check GM HIGH TECH PERFORMANCE's website for the most recent LT1 cylinder head Shoot-Out and at least one...

I am not convinced that Dex-Cool is "bad" for my (or my son's) engine.. Nor have I had any problem or negative experience in using Dex-Cool. It's obvious that you're certainly adamant in your condemnaton of Dex-Cool, however I don't share your view. In the future, should I experience a...

In spite of all the posts I've read where Dex-Cool has met with negative comments, my 96 and my son's 96 both have been runnig Dex-Cool Orange for a combined over 200,000 in miles with absolutely no problem. However, if there's more/new information on that coolant I'd like to know. So if GM...

The stock balancer/damper is actually two pieces joined together by what GM refers to a elastomer. It's like a rubber and over time the rubber hardens, cracks and separates. When that happens the outer portion will move independent of the inner portion which is attached to the crank. It's a...

My 96 Owmer's Manual states to specifically use Dex-Cool ORANGE (why you guys refer to it to RED is a mystery to me) and must be silicate free. It's good for 5 years or 100,000 miles and should meet GM Spec 6277M. Info on my Prestone bottle shows it meets all those specs. Don't go by BRAND...

My son's stock 1996 LT1 643 heads don't have guide plates of any type. Not even the ones so often referred to as factory installed for assembly purposes. None. Jake West Point ROCKS! Nation's TOP COLLEGE per Forbes Magazine!

No, that's not how it's done. The programming in the car's computer needs to be changed; re-programmed to change fuel and timing maps, etc., that are programmed into the computer from the factory. Cost varies, but I paid $175 Merely disconnecting and re-connecting the battery won't get...

Here's what I read is the story behind the LT4 Module: When GM decided to use roller rockers on the LT4 their testing showed excessive false knock. The address the Knock Module was modified (re-programmed) to be less sensitive to the additional noise (vibration) caused by the RRs. So, yes, if...

The battery is new, about 3 months old. Alternator shows normal charing rate. I donl;t have any starting or drivability issue. I diconnected the battery yesterday and the SES light's now gone but I still don't know what caused it. I checked for a stored code by jumping 4 and 12 on the ALDL...

96 LT1. What would cause a steady SES light but no stored code? I posted on this issue on the General Board but I think I should have posted it here. Thanks, Jake West Point ROCKS!

96 LT1, Auto SES light began flashing then remained ON steady. Engine never missed a beat and NO difference in drivability. Yet, when I used the paper-clip method to determine the code, none was stored. Auto scanning showed - - -, in all modes so I can't trace the source. I shut down and...

That dove-tails into my thinking too; that ignition timing is referenced off crankshaft position and that moving the cam (advance or retard) is a mechanical change in the valve timing. However, I wasn't sure how the PCM programming would be effected by the mechanical re-phasing of the...

This has been kicked around on another Forum for a few weeks now, and so far, I've only found two guys who've degreed-in their LT1 cam. I'm surprised that so few have done so, but that's an issue for another day. For starters, I've degreed-in many, many camshafts over the years on both Big and...

First, I'd disconnect the battery for 30 seconds or so to clear any stored code. I'd then use the IAC resetting procedure to ZERO it but this time remove the paper clip/wire from the ALDL before starting the engine again. It''s often difficult to get the engine to idle with the IAC...

Makes me think something in the valvetrain. I'd pull the valve covers and have a look-see. Jake West Point ROCKS!

What's an easy way to tell which type I have? My car's a 96. Thanks, Jake West Point ROCKS!

Seems no one can help you with your problem and I can't either. My car's a Vette and doesn't have the lines you're referring to. Consider this a bump, hoping someone will chime in. Jake West Point ROCKS!
